. SPECIFICATION forming part of Letters Patent No. 426,838, dated April 29, 1890.

Application filed May 9, 1889.

' certain Improvements in Vertical Boilers, of

which the following is a specification.

The object of my invention is to so-construct a vertical tubular boiler having a large gratesurface and an extended heating-surface.

The main features of my invention are the special construction of boiler by which a large heating-surface is obtained in acomparatively small space, the location of the combustionchamber and grate beyond the vertical structure of the boiler, and the construction of the boiler of a series of enlarged chambers connected together'by tubes, thus dispensing with the stays usually employed in this class of boilers.

Referring to the drawings, Figure 1 is a sectional elevation of 'my improved boiler. Fig. 2 is a section on the line 1 2, Fig, 1. Fig. 3 is a section on the line 3 4, Fig. 1. Fig. 4 Fig. 5 is a section on the line 7 8, Fig. 4. Fig. 6 is a vertical section of my improved boiier slightly modified. Fig. 7 is a section on the line 9 10, Fig. 6; and Fig.8 is a section on the line 11 12, Fig. 6. 1 g

A is. the outer casing of the vertical-boiler fine, which is mounted on the casing oi the fire-box B, said fire-box projecting at one side,

so as to provide an. extended grate-surface,

and the fire-box being provided with the usual combustion-chamber B, grate a, and ash-pit a. The boiler is in the'present instance composed of three compartments or chambers D D- D having their top and bottom plates d (l rounded, as shown, so as to act as stays for the side plates, and thus dispense with the usual stays in the boiler. The chambers are connected together, and ,the lower chamber rests in the bridge-wall ot the fire-box. It will thus be seen that the casing structure is L -shaped, the horizontal portion containingthe fire-box and the vertical portion containing the boiler structure. At the rear of the bridge-wall and boiler is a second combustionchamber communicating-with the vertical flue portion of the boiler-casing. The chambers D D" 'areconnected together by a series of vertical tubes which are-expanded into the Serial No. 310,102. (No an Figs. 1 and 2, and the chambers D D are connected together by side tubes G.

Defiecting-plates b b extend from the boilercasing to the center of the flue W, first from one side and then from the other side, so as to direct the products of combustion in a zigzag course around the boiler, thus utilizing as much of the heat as possible. 5

The chamber 1) is divided by a plate d, forming in its upper part a steam-dome D as shown in Fig. 5. This steam-dome is connected to the remaining portion of the chamher-D by the upper of a series of pipes e e,

face on which water may lodge at anytime, the pipes being, in .fact, segments of c1rc1es. These pipes extend, as shown in ,F1g.-1, 1n spiral courses around the entire periphery of the chamber'D so that the products of com,- bustion gain access to all portions of the pipes, thus increasing the heating capacity of the boiler.

each chamber D D D so that access can be had to the interior of the chambers in case of any alterations or repairs being required. Man-holes c o are also provided in the caslng A of the flue-a for the same purpose. Con1-' outlet pipe f, and a smoke-stack A communieateswith the upper end ofthe flue A.

or more doors may be used for firing, as shown -in cross-section, Fig. 2.

By having the top and bottom plates of the chambers rounded the tubes E or F at the center are necessarily short-er than the tubes at the outer edge, so that the tubes are readily removed from the structure in making re-' airs.

In Fig. 6 I have shown 'the chambers D D and the'chambers D D are also connected toof helical tubes-F The chambers D D D rounded, as shown, so as to leave no flat sur- The grate-surface may be enlargcd,ar 1d two connected by a central flue F, and also byalso connected by side tubes G, as shown in municating,with the steam-dome 1) is a steam-,

the base-section and firc-box'ivith a vertical easing mounted thereon, chambers I) I) D vertically arranged: Within said casing and base, with connecting and circulating tubes uniting the several chambers, substantially as specified.

2. The combination, in a vertical boiler, of the base and laterally-extending fire-box sec tion with a vertical casing, with chambers D I), vertically-arranged tubes connecting said chambers, said chamber D being, set in the bridge-wall, while the chamber D forms a continuation of the roof of the combustionchamber, substantially as specified.

3. The combination, in avertical boiler, of the base-section and laterally-extending firebox with a casing mounted thereon, chambers I) D D arranged in a vertical line with tubes connectingthe chambers,anddeflecting-plates in the flue formed by the casing, whereby the products of combustion are defleotedfrom a straight path, substantially as specified.

4. The combination, in avertical boiler, of the laterally-extended fire-box,with the chambers D D at the rear of the grate of said firecombustion chamber,
